SharePoint 2010 Search 101

SharePoint 2010 has three different types of searches. SharePoint foundation server search, SharePoint server search and SharePoint FAST search. The FAST search requires additional license = $$$.

Not sure how FAST search works. For SP foundation and SP Server searches, each has its own web app pool. By default, the app pools are named as GUID (yike). The search also has their own backend databases. One for crawl, one for application, and one for property store.

Here is a link to get search related PowerShell cmdlets.

Here is a microsoft link to show you how to remove URL from search, if needed. This can be very useful, when you want to hide any sensative information from searching.

After I installed my SharePoint 2010 and started all the services, I got errors in my event log to tell me that "The mount operation for the gatherer application has failed because the schema version of the search gatherer database is less than the minimum backwards compatibility schema version supported for this gatherer application." After done some research online, I found out that I needed to upgrade to SharePoint SP1. Here is a useful Micorosft link with some detailed steps for the upgrade. In order to find out if your environment requires an upgrade or not, you can run this PowerShell command - "(get-spserver $env:computername).NeedsUpgrade". If it returns TRUE, time to upgrade. After install SP1, need to run "psconfig –cmd upgrade –inplace b2b -wait".

All above just touched surface of SharePoint search. It is a BIG topic on its own. I recalled the days I served as server engineer to install TREX to crawl and index SAP documents. It was not an easy task. New to SharePoint 2010 search. I guess that the fun / pain has just started...
